Pluto's heart of ice is even colder than we originally thought. NASA recently revealed that the lonely planet, which we so cruelly voted out of our solar system in 2006, contains far more water ice ...

Data from NASA’s New Horizons spacecraft point to more prevalent water ice on Pluto’s surface than previously thought. A new false-color image, derived from observations in infrared light by the Ralph ...

In recent months, there’s been growing evidence that Pluto is hiding a liquid water ocean beneath its frozen surface. New models by researchers at Brown University support this hypothesis, and take it ...

Irving Berlin surely didn't have Pluto in mind when he wrote "Blue Skies" in 1926—four years before the dwarf planet was discovered by astronomer Clyde Tombaugh—and it's unlikely that Ella Fitzgerald, ...

Massive ice volcanoes found on the former planet Pluto hint at the possibility of liquid water located deep beneath its surface. The volcanoes, multiple miles high, have resurfaced large areas of ...

Planetary scientists have suspected for months the presence of water on Pluto in the form of towering ice mountains (shown below) — some of which rival Earth's Rocky Mountains in height. But it wasn't ...

This false-color infrared image from NASA’s New Horizons spacecraft shows water ice concentrations on Pluto. The left image is the result of an initial analysis, and the right image has been ...

New maps released by NASA show that the dwarf planet has more water ice than previously thought. The data taken by the New Horizons spacecraft captures more prevalent frozen water on Pluto's surface, ...

The pictures that came from New Horizons' flyby of Pluto have set off a scramble to make sense of the dwarf planet's terrain. Pluto's clearly geologically active, with mountains and fresh surfaces ...
